Saturday at the Disney D23 Expo, Marvel Studios premiered a secret trailer for the May 2018 Avengers: Infinity War. After the people in attendance were treated to that gem, they also got the first look at the four new villains for the movie, the Black Order – the four “children” of the mad titan Thanos.

When the entirety of the Marvel Cinematic Universe come together to battle Thanos, he will not come alone. We have already met two of his "children" in the "Guardians of the Galaxy" films, Karen Gillan’s Nebula and Zoe Saldana’s Gamora. Those two have broken away from the mad titan, but the four who remain have yet to do so, and the sound like the are just as brutal as Thanos himself.

Here are the new characters, who truly are fresh off the shelf. They were only introduced to the Marvel Comics world in 2013:

Corvus Glaive – This enforcer, whose job was to shakedown planets for gifts that would enrich Thanos, was immortal as long as his mystical blade remained unbroken. He was married to …

Proxima Midnight – This warrior used her spear – which was forged from a sun trapped in an alternate reality – to launch a shattering attack on Black Panther’s nation of Wakanda.

Ebony Maw – Not the most powerful of the Black Order, but a brilliant and manipulative thinker who wields power of persuasion over most beings. He famously tangled with Doctor Strange in the comics.

Black Dwarf – Don’t let the name fool you. This brawler is physically hulking and has superhuman strength and nearly impenetrable muscle mass. The bigger they come, the harder they fall is a cliché – but it may apply here.

Performers for these creatures haven’t been announced, but the characters will at least partly be performed via motion capture.
